Proshare Revolutionary Achievements in Advanced Reverse Osmosis Membrane Technology
Proshare proudly unveils a groundbreaking innovation: a new era of reverse osmosis membranes, meticulously engineered through polymer interface nano-self-assembly technology. This cutting-edge advancement overcomes the limitations of traditional reverse osmosis membranes with two pivotal breakthroughs:
Ultralight Separation Layer: Utilizing advanced polymer interface nanotechnology, our team has remarkably thinned the separation layer to an extraordinary extent-at least three times slimmer than conventional polyamide thin films, which were previously confined to 100 nm. This revolutionary leap dramatically boosts water flux, leading to a significant increase in permeability.
Enhanced Performance and Durability: The integration of nanoparticles with specialized hydrophilic polymers catalyzes transformative enhancements in membrane hydrophilicity, anti-fouling capability, durability, and oxidation resistance.
Compared to traditional polyamide reverse osmosis membranes, Prosharehas achieved breakthroughs in four critical domains:
Self-Assembled Nanocomposite Film Technology
By seamlessly merging nanometer-scale precision control with nano-doping modification, we create ultra-thin, meticulously ordered separation layers using polymer interface nanotechnology. This approach surpasses the constraints of conventional polyamide membranes in both thickness uniformity and material variety.
Enhanced Water Flux and Superior Energy Efficiency
Through mastery of the layer-by-layer self-assembly process, the functional layer's thickness is precisely regulated, achieving a remarkable 3x reduction compared to traditional membranes. This breakthrough results in over 3x higher water flux and 30% lower energy consumption.
Innovative Polymer Materials with Exceptional Chemical Stability
Transcending polyamide boundaries, our team employs state-of-the-art hydrophilic polymers, such as modified polysulfones, in combination with ceramic-organic hybrids. These materials offer unparalleled oxidation resistance (withstanding exposure to 10 ppm chlorine) and pH resilience (maintaining stability across a pH range of 1 to 12).
Anti-Fouling Surface Mastery
The superhydrophilic surface (contact angle <10°), enhanced by nanoparticle reinforcement, reduces organic fouling tendencies by 50%, extends chemical cleaning intervals from 3 to 6 months, and cuts maintenance costs by 40%.
